Gyms and big studios hand new trainers a stack of client paperwork templates on day one. Independent trainers — the ones who go solo, train out of a home gym, outdoor space, or a client’s garage — usually don’t get that stack, and end up either skipping it entirely or improvising something in a Google Doc the night before a first session. Skipping it is the riskier of the two options: it’s the paperwork that protects you if a client gets injured, disputes a charge, or no-shows repeatedly.

Here’s what that stack should actually contain.

1. Client intake form

Basic contact info, training history, current activity level, and goals. This is the form that lets you actually program something appropriate instead of guessing — not a legal document, just the foundation everything else builds on.

2. PAR-Q (Physical Activity Readiness Questionnaire)

A short screening questionnaire — heart conditions, chest pain, dizziness, bone/joint problems, medication, pregnancy — that flags whether a client should get a doctor’s sign-off before starting an exercise program. The standard PAR-Q format is widely published and well-established in the fitness industry; the point isn’t to diagnose anything yourself, it’s to know when to say “get cleared by your doctor first” instead of guessing.

3. Liability waiver / assumption of risk

The document a client signs acknowledging that exercise carries inherent risk and that they’re choosing to participate anyway. This is the one trainers most often skip because it feels adversarial to ask a new client to sign something about injury risk on day one — but it’s exactly the document you want in place before anything goes wrong, not after.

4. Session agreement

What’s actually being sold: session length, price, package terms, what’s included (programming, in-session coaching, between-session check-ins) and what isn’t. Without this in writing, scope creep (“can you also just quickly look at my diet?”) and pricing disputes both get harder to resolve cleanly.

5. Cancellation / no-show policy

How much notice is required to cancel without charge, what happens on a no-show, and whether packages expire. This is the single most common source of awkward, unpaid conversations for solo trainers — having it in writing and referencing it (rather than negotiating it fresh every time) makes enforcing it far less personal.

Plus: a tracker

Once you have clients signed up, you need somewhere to log sessions completed, package balances remaining, and renewal dates — otherwise “how many sessions does this client have left” turns into a memory exercise.

A ready-made bundle

We put all five documents plus a 3-tab client/session tracker spreadsheet together as the PT Business Paperwork Bundle — 8 USDC or 16 POL on Polygon, no account, no subscription, no KYC, a one-time download. Every document carries an explicit “this is not legal or medical advice” disclaimer, because it isn’t — a template can save you from starting with a blank page, but it can’t replace a lawyer reviewing your specific liability exposure or a doctor clearing a specific client. If you’re training clients with any significant health risk factors, get the waiver reviewed by someone qualified in your jurisdiction before relying on it.

If you’d rather write your own versions using the five-document checklist above, that works just as well — the point of this post is the checklist, the bundle is just a shortcut for not starting from zero.
